    searched the forums, but found older threads such as the alienware one.
    In that guide the poster used a blob of as5 on the cpu and other parts of the heatsinks, is this the correct way?

    I ask because I have seen the as5 guide and it says you must put a 'straight line' above the cpu, does this just mean a straight line ONLY, or does it mean after applying this straight line, to evenly spread it?

    You need to spread it all over the CPU-GPU die. Don't leave any portion of the chip dry.

    Uh, no. That is NOT the way to apply AS5. Arctic Silver is very specific on how their AS5 should be applied. Depeding on the manufacture of your CPU (AMD or Intel) and the type of processor it is (Single, Dual, or Quad core), Arctic Silver provides detailed instructions on their site on how to properly apply AS5.

    You might want to check out the following link on how to apply AS5, Ramgen. Giving bad advice like this with obviously no experience with AS5 is just plain ignorant.

    AS5 Thermal Compound Instructions

    It means to apply a straight line, and NOT evenly spread it out afterwards. With a straight line of TIM applied and the heatsink placed onto the CPU, the AS5 will evenly distribute itself across the CPU die surface due to the weight of the HSF.

    Who told you that it is a bad advice???

    I have been using it like that for several years and it works perfectly fine Mr. Smart.

    Below is taken from the link that you have posted: (large exposed cores without heat spreaders)

    "Spread Arctic Silver 5 over the CPU core as shown in the photo to the right. The small amount from the photo above has been carefully spread over the top of the core using a single edge razor blade. A razor blade or the clean edge of a credit card can be used as an application tool. You may use whatever tool is available as long as it is CLEAN and allows you to control the application area and thickness."


    This is exactly what I have said above, right?

    Thanks guys.
    I believe you are both right, depending on the CPU type.
    ramgen is talking about "single core exposed cpu" i believe?
    garetjax is talking about "dual core with heatspreader" which is the one i'm after. ;)

    So i just apply the "line" and affix the heatsink back on, and the compression should spread it evenly for me? note this is a laptop CPU T7500

    For an Intel Mobile CPU, you just put a tiny blob or line or anyway you want, but not more than a grain of rice, and then spread the paste evenly on the die with a business card or credit card etc.

    Should look like this

    Honestly it doesnt matter how you apply the paste, sure their are tons of methods but everyone is partial to their own.
    Arctic silver like any other thermal paste is designed to simple fill the air bubble voids which are made when two "flat" objects are put together. No matter how flat the cpu or heatsink base their will always be pockets of air between the two. So the paste is their to force the air bubbles out and fill the space the air took with a more conductive material, which in most cases is copper or silver or whatever they use in today's pastes.

    As long as you put a grain of paste on about the ize of a piece of rice you are fine.

    Thanks, should I assume my T7500 to be like that?

    The original poster does not have exposed cores on his CPU. By reading his original post, you are able to discern that he was not using exposed cores because his description of using a single horiztonal line of AS5 is consistent with Intel dual and quad core processors covered with a heatspreader.

    Yes, for the most part. Although, I frown on the use of credit cards or razor blades for spreading TIM. I've gotten into the habit of using latex gloves or a finger in a sandwich baggie to spread TIM as it does an extremely good job while keeping your fingers clean.

    Thanks for the replies
    these are now my idle temps after being on for a few hours, and also my MAXIMUM temperatures after playing like 2 hours of counterstrike non-stop.
    It cools back down to idle temps quickly too now after exiting game

    previously idle was around 60 for cpu and max around 90 after counterstrike with gpu never below 64, and peaking 78 after gaming.

    (as5 on both gpu's and the cpu.)

    I just put a glob on and spread it around with a razor blade. I put the heatsink on then take it off to make sure every part is coverd if it is then i put it on and reassemble the laptop.
